NOZZLE TIP Filed June 30, 1935 dam mm Patented July 3, 1934 UNITEDSTATES PATENT OFFICE 1 Claim.

My invention relates to improvements in nozzle tips for fire hose,garden hose' and liquid sprays of all kinds.

The primary object of the invention is to provide a nozzle tip forsprayers having adjustable means for regulating the discharge of watertherefrom, whereby the size of the stream of water discharged may bechanged, as may be desired.

A further object of the invention is to provide a device of theabove-mentioned character which is simple and durable in construction,reliable and eflicient in operation and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawing, forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

Fig. 1, is a side view of the nozzle tip with the outer end in sectionto show my invention,

Fig. 2, is a cross section taken on lines 2-2 of Fig. 1,

Fig. 3, is a cross section taken on lines 3-3 of Fig. 1, and,

Fig. 4, is an end view of the same.

In the drawing, wherein for the purpose of illustration, I have shown apreferred embodiment of my invention, the numeral 5, denotes the bodyportion of the nozzle tip having internal screw-threads 6 at its innerend, for connecting the nozzle to a fire hose nozzle or the like. Thebody portion is gradually reduced towards its outer end, forming arestricted discharge passage 7, which opens into the eccentricallyarranged enlargement 8. The enlargement 8 is provided with externalscrew-threads 9 to receive the screw cap 10 which covers the outer endand rotatably mounted on the inner side end of said bore, a valve diskrotatably mounted of the cap is a valve disk 11 having a series ofvarious size apertures 12, arranged concentric to the axis of the disk,adapted to register with the discharge opening 13 in the cap. The valvedisk 11 is mounted on the inner end of the pin 14 journaled in thebearing 15 through the center of the cap and attached to the outer endof the pin is a finger knob 16, whereby the valve disk is turned.

In operation, the stream of water discharged from the nozzle tip may beregulated by turning the valve disk 11, to bring the different sizeapertures 12 into register with the discharge opening 13 of the cap. Inthis way the nozzle tip can be adjusted to deliver a solid stream ofWater or a fine spray.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same and thatcertain changes in the shape, size and arrangement of the parts may bemade without departing from the spirit of the invention or the scope ofthe subjoined claim.

Having thus described my invention, I claim:-

A nozzle tip comprising a body having a longitudinal bore therethroughtapered towards its discharge end, a circular enlargement formed at thetip of the body and eccentric therewith, providing a large waterreceiving chamber communicating with the discharge end of said bore, acap threaded on the outer end of said enlargement adjustablelongitudinally to alter the size of said chamber, said cap having adischarge opening in alinement with the discharge on the inner side ofsaid cap having a series of difierent size apertures and means forturning said valve disk to bring said apertures into register with thedischarge opening of said cap.
